Knock sensor is designed to detect when the combustion in car is not being properly controlled.A knock sensor uses an internal element that is extremely sensitive to vibration and will detect when the pressure wave from the combustion hits the cylinder wall before it is supposed to.When the sensor detects incorrect noise from internals of the motor it will retard the timing in order to protect the engine.The sensor has been designed to act as if mechanic was listening to the engine and keeping an eye on the things for the driver.
